BOLSTER CASING FOR SPINNING SPINDLES. l

`Application filed February 9, 1923. Serial No. 618,146.

T 0 all whom t may concern:

Be it known that l, HJALMAR Gr. CARLSON, a citizen of the United States, residing at Worcester, in the county of lVorcester and State of Massachusetts, have invented a new and useful Bolster Casing for Spinning Spindles, of which the following is a speciiication.

This invention relates to a bolster casing intended to beI used for holding a spinning spindle. A The principal objects of the invention are Vto provide a casing of this kind formed from sheet metal and provided with a projection around itintegral with the sheet metal of which the rest of the Vcasing is made and having an oil-receiving depression in it; to provide this in such form that it can be constructed by die-pressing operations and at a very rapid rate, materially decreasing the cost of production and also doing away entirely with the projection ordinarily employed at this point on castiron bolsters; and to provide means by which the bolster can be adjusted minutely to an exactly ver tical position and held in such position positively and firmly.

Additional objects of the invention will appear hereinafter.

Refercnce is to be had to the accompanying drawings, in which- Fig. lis aside view of a spinning spindle located in a bolster casing constructed in accordance with this invention;

Fig` 2 is a central sectional view of the same; Fig. 3 is a sectional view of the upper part of the 'bolster casing on the horizontal line of Fig. 2; y

Fig. 4 is a similar view showing the doer guard in position, and

Fig' is ay side elevation showing the operationofthe doffer guard.

I have shown the invention as applied to an ordinary rail 1() of a spinning machine, this rail having a perforation 11 therethrough for the bolster casing 12. This perforation is larger than the intermediate por-` tion fof the bolster casing so as to permit of adjusting the casing to the eXact vertical position.

TheV bolster casing is formed of a single are 'sollocated Vthat when the piece of sheet metal pressed up in dies to provide the desired construction. 1t co-mprises a lower end 13 closed at the bottom by a bottom wall 141 having an inward depression or step 15 therein for receiving the bottom end of the spindle. It also has an upper end 16 of substantially the same size and shape as the lower end but open at the top to receive the spindle. Between these two end portions 13 and 16 there is an intermediate portion 17 of a larger diameter,

screw threaded on its outside surface.

The twopart-s 16 and'l'? `have formed at their junction an oil cup 18. It is formed by two thicknesses of metal pressed first outwardly and theninwardly into contact with the outer layer to form this annular oil cup. This provides a circular space surrounding the bottom. of the upper portion 16 of the bolster casing to receive oil put in intentionally or accidentally discharged over the open end of the bolster casing. The wall is pro vided with a perforation 19 to allow the oil to run down into the interior where it will lubricate thespindle, being received in the space between the spindle and the enlarged intermediate portion 17 in the casing. This oil cup 18 is therefore of annular form having double walls and a horizontal rim.

A flat dolfer guard plate 2O is arranged to rest on the top of the oil cup. This plate has a downwardly extending flange 21 all around it. It has a central perforation 22 for receiving thelower flange 30 on t-he bottom of the whirl 31 of the spindle. The oil cup is provided with a pair of headed studs 23 located diametrically opposite each other. the outer walls of the cup being preferably slightly flattened where they are provided to receive a pair of opposite flanges 21 parallel to them. These flanges are provided `with vertically elongatedA slots 24 through which the studs 23 pass, and they plate 20 rests onthe top of the cup 18 these slots extend below the studs.

On one end of the vided a `cylindrical offset 25 in which' is permanently fixed a wire 26 which extends upwardly and is provided with an inwardly and downwardly `extending hook 27 constituting a doifer guard and projecting up plate `20 there is pro-- vover the upper horizontal flange 32 of the Whirl normally. Y

The lower surface ofthefcup 118 is convex preferably and under this is'located a sheet metal Washer 28 which has a concaveupper surface fitting the bottom of the cup. The

' bottom' of the ouppedeldge ot this Washer is Squared up and rests horizontally on the top ot' the rail 10. Underneath the rail there is another cupshapedsheet metalwasher 29.

and fitting the convex lower surface of it is a nut 33 which has a'fconcave-or internal spherical upper surface.

' In attaching-fthe devicef'tothe rails-the `-tivelyin thatposition.` This is'fpossiblef on accounto the' *tact that the hole or-pe'roraf tfionllis larger thantheintermediate'.porf tion'l? otthe bolstercasing5 so as tovraliow somefplay Also, oniacoonnt of the/conical' orisphericalisurfaces of thewvashersythe eas-V fing can be tilted slightlyeunti'l it is brought' loosely in this Way this plate 2O rests nor- Y mally in a horizontal position and it `dis-V placed in :either Way-it"will;nonbeing released fdrop back itof-thei cup "-'atfonce by gravity. Y

Furthermore, the lower flange on the whirl extends down" through the. opening 22 inthe plate 20 and theplate'itsel minimizes the splashing 'lot' oil caused by its flange. A n-y oilthat vflows over the top of the bolster 1 casing Wlll run down into the oil cup andVV beusedigagainfi-n oiling the spindle, and any oil that is put in the cup intentionally can also be used inthe same QWay.
